A micro gas burner is provided that generates a stable, pre-mixed flame that produces little to no soot or unburned hydrocarbons. The gas burner includes a fuel inlet, nozzle, oxygenation chamber with at least one air inlet, a mixing chamber having a frustoconical inner wall, at least one permeable barrier and a flame holder. The gas burner thoroughly mixes fuel and entrained air to form a nearly stoichiometric mixture prior to combustion. The gas burner mixes the fuel and air so thoroughly that it requires a lower fuel flow rate than would otherwise be necessary to produce a stable, pre-mixed flame. The gas burner may include an optional flame tube with an optional exhaust port in which a flame is contained and sequestered from diffusing air.

An apparatus for cooking food with infrared radiation includes an infrared energy emitter for emitting the infrared radiation, and a grid in close proximity to the infrared energy emitter. A first side of the grid can be for supporting the food at a position so that at least some of the infrared radiation will cook the food. A second side of the grid can be sufficiently close to the emitting side of the emitter for substantially restricting any airflow in any space between the second side of the grid and the emitting side of the emitter. Partitions of the grid can operatively segregate the emitting side of the emitter into segments, which can provide a substantially uniform distribution of infrared radiation.

A burner apparatus comprises a conduit adapted to convey preheated oxidant and having outlet and inlet ends, and a conduit adapted to convey preheated fuel and having outlet and inlet ends. The conduit adapted to convey preheated fuel is substantially parallel to the conduit adapted to convey preheated oxidant. The conduit adapted to convey preheated oxidant is positioned substantially vertically above the conduit adapted to convey preheated fuel. The conduit adapted to convey preheated oxidant and the conduit adapted to convey preheated fuel each are positioned within its own respective elongate cavity in a refractory burner block. Each of the conduits are positioned in their respective cavity such that a substantially annular region is present between an outer surface of each conduit and its respective cavity. Each conduit inlet end extends through a respective plenum for receiving an ambient temperature fluid, the plenums adapted to pass the ambient temperature fluid into the respective annular regions.

The present invention is a radiator element composed of a metal foam for use within a radiant burner. The radiator element is comprised of a homogenous network about a plurality of inter-connected cells thereby forming a gas-permeable metal foam. The homogeneous network may be composed of a metal or metal alloy capable of withstanding combustion temperatures typical of fuel-air reactions and resisting damage produced by flashback. Inter-connected cells include irregular-shaped voids, circular-shaped voids, and combinations thereof.

This invention describes an improved gas burner assembly that can be adapted to attach to a range top or cooktop, or the floor of the range and can draw air from either above the range top level by external vents or from below range top level through an open style mixing cup. The invention uses a plurality of different flame rings to provide the user a wide variety of temperature settings starting from a low intensity simmer to high intensity cooking heat. The gas burner also utilizes a cover plate of transparent or translucent, heat proof material that allows the user to observe the interior of the burner to see if any of the flame rings have been ignited. The cover plate also transfers heat from the internal flame rings to the cooking utensil which provides a more uniform transfer of heat to the utensil.

A heating unit has a cartridge that constitutes a single component, which can be readily removed and replaced with a new cartridge. The cartridge is a plurality of non-flammable layers bound together in a border. The layers include a stainless steel mesh located above a layer of ceramic wool. With the cartridge, replacement can be accomplished in approximately fifty minutes compared to a downtime of a week or more previously.

In an embodiment, a system includes an end cover and a liquid cartridge. The liquid cartridge is configured to mount in a fuel nozzle of a turbine engine, wherein the liquid cartridge comprises a one piece flange configured to couple to the end cover, wherein the flange comprises a water inlet, an air inlet, and a fuel inlet.

The invention relates to a burner (1) for cookers, suitable for burning gas, comprising at least two gas crowns, of which one central one and at least one circumferential one, a mixing chamber (13) with Venturi effect, ducts for entry of the primary air and radial ducts (9) for feeding the gas / primary air mixture to the said at least one circumferential crown, comprising a body (3), a head (2) and a separation element (4) that breaks up the internal space into ducts for entry of the primary air and ducts for distribution of the gas / primary air mixture.
